Indices and technologies of cell phone jammerare on the world’s level
More serious interference range will be further expanded, and even interfere with the base station to a standstill near the district, factories, large-scale units are strong, people will anger quite heavy; by residents and Mobile, China Unicom, Telecom and other operations of the complaint, and local radio management department of the prison to work these issues to bring some negative effects , disrupting the harmonious relations between police and the public. Power of each channel can be adjusted according to the operational environment for cell phone jammer.3) The system is running stable: good times and bad, is not high reliability, fault-prone. In particular, summer and fall, a large number of equipment failures damage, even after the replacement of large equipment are still unable to achieve the desired shielding effect; for people with ongoing maintenance, labor life a waste of money, just like chicken. The poor performance of the prison phone system several shielded main four. The poor performance of the prison phone system shielded a few main reasons.The power of mobile phone jammer for CDMA is 50W. First, the subjective awareness of mobile shielding system 1) lack of proper shielding the prison system and a comprehensive understanding of the common market between the civilian nature of cell phone jammers difference. The prison system is a set of shielded communication technology, radio transmitter receiver technology transfer, electronic warfare technology, equipment, comprehensive technical and performance indicators for the perfect combination of product, not the general civilian use a large number of mobile phone jammers easy distribution to use. 2) lack of system cost and input-output ratio of the integrated and scientific analysis.This kind ofcell phone jammeris used in places where requires high demands and far distance. People often make the minimum investment funds to produce the greatest results, however, ignored the basic technology in the product a reasonable investment. As well as procurement can not use a fundamental technical requirements for low-end prison project equipment products, is intrinsically flawed, leaving endless risks for the future. 3) of the sales staff in front of the enterprise market driven by economic interests to exaggerate the strength of corporate and product quality, to make myself do not understand the commitment and can not be achieved, have a problem if in the future, and placed their own good social skills, customer relationships to make up hope the problem the product itself (and even some equipment suppliers knowing the product itself seriously flawed).The jamming area ofcell phone jammercould be adjusted precisely. Second, mobile shielding device itself because 1) At present, many domestic enterprises shielded equipment production and sales, in product development application did not put a lot of manpower, financial resources, without a corresponding increase in key technologies, instead of using the OEM, generic, low-cost, low performance, low-price strategy, selling mass-produced, widely exaggerated marketing campaign depends, in the general civilian market is not critical to achieve a certain profit, while in prison want high standards, high demand, high reliability market segments occupied place, but eventually will shield the prison phone system incalculable loss. .
